The two-stage solid-propellent Inertial Upper Stage made two burns. The first stage burn occurred shortly after deployment from Discovery, and placed the satellite into a geosynchronous transfer orbit. At 04:30 on September 30, it reached apogee, and the second stage fired, placing TDRS-C into geosynchronous orbit. At this point it received its operational designation. Although the TDRS-2 designation had not been assigned, TDRS-C was given the designation TDRS-3 as NASA did not want to reuse the designation which had been intended for the STS-51-L payload.[6] It was briefly placed at a longitude 151° West of the Greenwich Meridian, before being moved to 171° West before the end of 1988, from where it provided communications services to spacecraft in Earth orbit, including Space Shuttles. In 1990, it was relocated to 174° West, and again in 1991 to 62° West. In 1994 it returned to 171° West.[7][8] In June 1995, it was moved to 85° East, from where it was used primarily for communications with spacecraft such as the Compton Gamma Ray Observatory and the Hubble Space Telescope.[7][9] In October 2009, as NASA began decommissioning TDRS-1, TDRS-3 was moved to 49° West,[10] where it remains in storage as of 2014.[11]
